This invention relates to an improved printing or recording device.

It is the principal object of the invention to provide an arrangement capable of very high speed of operation, so that a printing or recording device, such as a typewriter for example, may be operated at a speed equivalent to the rate attained by the fastest form of stenography. The advantage of an arrangement of this kind is obvious, inasmuch as it allows of high speed dictation direct to the typewriter.

It is a further object of the invention to provide a device capable of simultaneous control over any desired number of printing devices. In this way any number of original copies may be produced simultaneously.

While the invention has been disclosed and will be described in combination with a typewriter, it is to be understood that the invention is not to be limited by the disclosure, as the inventive idea is capable of a variety of expressions, as for example, in the control of a linotype machine, or printing telegraph. An understanding of the invention may be had from the following description and appended claims, reference being had to the drawings.

Fig. 1 shows the In allotter with various register relays.

Fig. 2 shows register relays. Fig. 3 shows a controlling keyboard. Fig. 4 shows initial relays for the translating device. Figs. 5 and 6 show final relays for the translator.

Fig. 7 shows miscellaneous translating relavs.

Fig. 8 shows various relays and magnets for controlling the operation of the typewriter. a

Fig. 9 shows the remaining final relays for the translator.

Figs. 10 and 11 show test relays and conmeeting relays.

Fig. 12 shows the vowel relays. Fig. 13 illustrates the typewriter keyboard.

Fig. 14 shows the various code combina- 5 tions necessary to provide an arrangement The drawings when arranged as shown in Fig. 17 show so much of an organization of circuits and apparatus as is necessary to an understanding of the invention.

From the foregoing table, Fig. 14, it may be seen that the keyboard is a combination of a directly controlling keyboard and of a permutation keyboard in which a combination of keys may control the selection of a single letter. Since the keyboard may be used either to exercise direct control or may function as a permutation keyboard, it may properly be said to be a dual function keyboard.

It should be noted that while'electromagnetic apparatus and suitable control circuits have been made use of in the particular embodiment of the invention disclosed, the invention is capable of development in other forms.

General desm'z'ptz'on Devices have hitherto been produced with a View toward the accurate reception of rapid dictation. A well known device of this character is shown in U. S. Patent N 0. 1,280,743, to W. S. Ireland, October 8, 1918. This de- 3 vice is successful in enabling its operator to take dictation at an extremely high "speed, and records the subject matter in typed form in accordance with a special stenographic code. A device of this nature, however, solves only a part of the ultimate problem, since its record requires translation by means of human intelligence, with accompanying typing into complete and commonly intelligible form.

By means of the present invention a keyboard essentially similar to that shown in the above mentioned Patent N 0. 1,280,743 may be used with the attendant capability of Very high speed of operation. An automatic translating and controlling device is supplied, by means of which the record is translated from stenographic to complete form, and a typewriter or other recording device is operated to record the subject matter in the form originally received by the operator.

Referring now to Fig. 16, a manual controlling device, preferably a' keyboard, is shown. Ten registering devices have been shown, and may be successively associated with the controlling device by means of an In progression switch. As many registering devices as are required may be supplied.

When a combination of keys is operated, the record is taken and locked on the register allotted by the progressionswitclnwhichthen advances to assign a new register. After the last register has been set, the first one is again taken for use. Enough registers must be supplied so that there will always be one available.

The registers deliver their respective records to the recording, translating and automatic controlling device, with which they are successively associated by means of an Out progression switch, or allotter. As soon as a register has delivered its record to the translating device, such register is released and is available for receiving a new record from the keyboard, when associated therewith by means of the In progression switch.

'When a record is received by the translating device, it translates such record into its original form, and causes it to be typed by means of an electromagnetically operated typewriter. As soon as this operation is completed, the Out progression switch advances to associate the translating device with the next register.

Referring now to Fig. 3. a brief description of the controlling keyboard will be given. The keyboard maybe remotely placed with respect to the remaining apparatus if so desired.

The letters STKPWVHR are to be operated by the fingers of the left hand and are known as the initial consonants. The letters EOAU I are the vowels and maybe operated by the thumbs of both hands. The letters FRPBLGTEDS are the final consonants and are to be operated by the fingers of the right hand. The above letters read and are recorded in the order given.

The keys may be simultaneously operated at one stroke. It is this simultaneous operation of the keys which makes possible the great speed of the device, as is obvious when- .the method is compared to ordinary typing in which the keys are successively manipulated. The keys are of a non-locking type, by which is meant a key that returns to its normal position as soon as finger pressure is removed.

To record the word skate, the letters S and K are operated by either one or two fingers of the left hand, the letter A and the space bar are operated by the thumb of either hand, and the letters T and E are operated by one finger of the right hand. A' single stroke is required to record the complete combination. A simple word of this nature requires no translation. It' will usually be necessary, however, to depress the keys in accordance with a code in order to record varlous letters, punctuation marks, etc. Fig. 14 shows a complete code in which the equivalents of the various combinations are indicated.

This code is developed from a practical study of the keyboard and its various possibilities. For example, the letters TPH can never be used as the start of any known word. This combination may therefore be assigned to any desired letter or symbol. In the present system, it isassignedto N when used as an initial consonant. The combination TPH is translated to cause the type-. writer to print N, as will be subsequently described.

The various special keys shown. in Fig. 3 are used to automatically control movement of the carriage, spacing, etc.

The circuits from the keys terminate in movable contacts of the In allotter as indicatedin Fig. 16.

It is believed that the printing can be ac: complished faster than the operator can set, the registers. However, if for any reason he, should get far enough ahead of the printer so that no register is available, heavill be apprised of this condition by means of a busy lamp associated with each register.

Other lamps are provided for various Sig naling purposes, as will be subsequently de-* scribed.

After a record has been received by the first register, a. short delay is introduced .to allow the operator to make a correction when necessary. This delay is produced by making the printing operation for the first register await the setting of the second register. In case correction is necessary, the operator may accomplish it by means of a wipe-out key.

Upon the termination of dictation,.suiii* cient time for wipe-out is introduced, after which the last word is printed.

Each register consists of one relay for each letter key on the keyboard. Miscellaneous control relays are provided for taking the record from the various auxiliary keys. 7

After the first register has been positioned, the record is transmitted to the translator, which also has a relay for each letter key and I miscellaneous control relays.

After the translator has received the rec- 0rd for a word or syllable, 22 conductors corresponding to the 22 letter keys are tested. This is done by means of 22 pairs of test re lays. The conductors, correspondin to keys that should not operate, are grouni ed, and the associated test relays energize. The conductors corresponding to letters to be printtest relays, which in turn releases the magnet, thus causing the operation of the other relay of the pair. The printing conductor is then extended to contacts of the next pair of unoperated test relays, whereupon a printing operation again takes place. This process is continued until the printing conductor has been extended through all the test relays, whereupon the allotter is advanced to associate the translator w ith the next register.

In many caseswords may be registered in several ways. Thus the word skate may be recorded with spacing, at a single stroke, or it may be recorded a letter at a time, as on the ordinary typewriter. It may also be recorded as a result of several operations, each of which registers part of the word. It should be noted that the proper sequence of the letters from left to right must be maintained regardless of which method is used.

A few of the large number of words which may be recorded at a single stroke are included in the following list: groin, chair, yearn, snatch, swear, swore, sphere, wreath, blond, speed, what, exact, float, fifth, breast, bread, cold, maid, raid,snore, exit.

The word frock obviously cannot be recorded in a single stroke since in the concluding letters C PL and K LGTE, so that an overlap of letters is produced.

Referring to Fig. 13, it will be noted that the designation has been omitted. This symbol is ordinarily used in place of the word at. In the present system the word at may be recorded at a single stroke, so that no saving would be introduced by the use of the abbreviation symbol.

The exclamation point has also been omitted from the keyboard, and no combination has been assigned to this particular punctuation mark, inasmuch as it cannot be recorded at a single stroke. On the ordinary typewriter, in printing the exclamation point, it is necessary to use the period, then the backspace, and then the single quotation mark. The same slow process would be required in this system, and it is felt that the period may be used during dictation, and that the quotation mark may be supplied later from an ordinary typewriter. It is also recognized that the exclamation point is very seldom used in normal dictation.

A detailed description of the operation of the device will now be given.

It will beassumed that the words the gem are to be printed. Including the necessary spacing, these words require 8 strokes on the ordinary t pcwriter. In the present system, they may e recorded in two strokes. The first stroke includes the spaceand the letters THE. The second stroke includes the space and the letters TKPWEGE, in which TKPW G (initial) and GE=M (final).

Before beginning operations it is necessary to depress one of the locking keys 723, 724 or 725. These keys control the line spacing, and when depressed remain in that condition, thus giving the operator an indication of the spacing being used. Ke 723 is used for single spacing, key 724 or double spacing and key 725 for triple spacing. It will be assumed that double spacing is desired. Key 724.- will therefore be depressed.

The depression of key 7 24 causes the space control switch (Fig. 8) to move to position 2, provided it was not already in that position. If we assume that the control switch was in position 3 at the time key 7 24 is de pressed, a circuit is completed for the return magnet 813. This circuit extends from grounded battery, winding of magnet 813, brush No. l and its third contact, lead 726, and contact of key 724 to ground. Magnet 813 is energized and locks in a circuit through its armature and contact to ground at an offnorma-l switch 814. The energization of magnet 813 releases a holding pawl and allows the control switch to return to its normal position, whereupon the off-normal contact 814 is opened and magnet 813 deenergizes.

The control switch is mechanically of a construction well known in the art of automatic telephony and needs no detailed disclosure or description. Contact arms are provided and arranged for motion int-o successive engagement with contacts arranged in an arcuate terminal bank. A ratchet and pawl mechanism, electromagnetically operated, acts as a motor for the device. Motion is against spring tension, and return movement at the end of each step is prevented by the holding pawl controlled by magnet 813. In addition to the brushes, the switch actu ates a lever which controls the spacing device on the typewriter (Fig. 15) and causes it to assume a desired one of its three positions in accordance with the setting of the control switch.

When the control switch reaches its normal position, a circuit for stepping magnet 812 is completed from grounded battery, winding of magnet 812, armature and back contact of magnet 812, brush No. 2 and its associated first contact, lead 727, and contact No. 4 of key 724 to ground. Stepping magnet 812 is energized and interrupts its own circuit to advance theswitch to position 2. In this position no circuit for the magnet 812 is found, and the switch therefore remains in this position.

The movement of the control switch to position 2 moves the space lever on the typewriter to position 2, which is the position for double spacing. Had key 7 23 been depressed, the control switch would have been brought into position 1 and the typewriter space lever would have been brought into position for single spacing. Similarly, key 725 prepares the typewriter for triple spacing.

The operation of the keys THE and space bar 28 causes the operation of relays 2T, 6H, 8E and space relay 10 in the first register.

The In allotter switch is shown in Fig. 1 together with miscellaneous control relays for the two registers.

Only so much of the method of interconnecting the keys and registers has been shown as is necessary to an understanding of the invention. The key T indicated at 30 is the only key whose contacts are shown connected to the allotter and the registers, and this key is shown for use with only two registers. It is to be understood, however, that as many registers may be provided as are required for the proper operation of the system.

The number of registers required will depend on the speed of the operator and the speed at which printing takes place. Enough registers must be provided to allow the operator to make strokes while the typewriter is undergoing various miscellaneous operations, such as automatically moving to a new page position.

The In and Out allotters in the present disclosure are arranged for cooperation with ten registers, and move over contacts corresponding to these registers in sequence. Since the wiring of only two registers has been shown, the present disclosure has been arranged to cause the allotters to'move from their second positions, over the remaining positions without stopping, and thus back to the first position. This is accomplished for both allotters by means of self-interrupting circuits for their respective stepping magnets as will be described hereinafter.

The allotters are mechanically so arranged that they will engage their first position contacts on the completion of the step which moved their brushes from engagement with the tenth position contacts.

The circuit for relay 2T may be traced from ground at the allotter switch, the No. 1 allotter brush and its first contact, conductor 2, contact 6 of key T, conductor 4, winding of relay 2T, conductor 5, winding of low resistance battery feed relay 6, to battery and ground.

Relay 2T is energized and locks in a circuit through its armature and contact, conductor 8, right armature and back contact of release relay 9, to ground. Relays 6H, 8E and relay 10 are operated in a similar manner, by means of contacts (not shown) controlled by the H and E keys and by the space bar 28. Relay 6 is energized in series with the above relays, and completes an obvious circuit for lamp 28 at its outer right hand armature. Whenever a register is in use, a battery feed relay corresponding to relay (5 is energized and a lamp corresponding to lamp 28 is lighted. The position of these lamps with respect to the keyboard may be seen in Fig. 3, where the lamps are designated register lamps. Thus the operator may rapidly note how many registers are idle and at whate rate they are being discharged. This information enables him to properly regulate the speed of operation of the keyboard. VVhen all registers are busy, a chain circuit for lamp 29 extends from grounded battery, lamp 29, outer left-hand armatures and contacts of the battery feed relays (each energized while its associated register is in use) in succession and to ground at the armature of the battery feed relay associated with the final register. The lighting of lamp 29 informs the operator that all registers are busy and that he has encountered a register which is not yet ready for use.

Contact 1 of key T energizes allotter magnet 11 in a circuit from grounded battery, winding of magnet 11, to ground. The allotter is a simple step-by-step switch and is arranged to advance upon deenergization of the magnet. When the keys are released. magnet 11 is deenergized and the allotter brushes are advanced into engagement with the second contact set, in which position the second register set is made operative. It should be noted that each key has a contact corresponding to contact 1 of key T, so that the allotter may be controlled whenever any key is depressed. The second register is now set by depressing keys TKPTVEGE, corresponding to the word fgem. The record is taken in a manner snnilar to that described for the first register. The relays for the second register have not been shown, as it is believed that they would merely serve to complicate the disclosure, inasmuch as they are identical with those shown for the first register. The second operation of the key set causes the energization of relays in the second register corresponding to relays 2T, 3K 4R BWV, 8E, 18G and 20E of the first register. The battery feed relay 14 and the space relay 30 of the second register are operated.

The fact that a record has been taken by the second register indicates that no corrections in the first record are to be made. Translation and printing of the first record may therefore proceed.

The multi-conta ct relay 101 is now operated in a circuit from grounded battery, winding of relay 101, conductor 15, right armature and contact 1 of relay 14, conductor 16, left contact and armature 2 of relay 6, conductor 17, contact and brush 2 of the out allotter, to ground. Itwill be assumed that the out allotter is in position 1, in which position connections are extended to the first register.

Relay 101 extends circuits from contacts of each relay in register I to the windings of corresponding relays in the translator circuit. Corresponding relays have. been correspondingly designated, with the prime applied to the translator relays for dlscrimmating purposes.

The energization of relay 101 causes the record on the first register to be transferred to the translator relays, 2T, 611, (Fig. 4) relay 8E (Fig. 12), and space relay 703 (Fig. 7). The circuit of relay 2T may be traced from grounded battery, Winding of battery feed relay 701, conductor 702, conductor 401, winding of relay 2T, conductor 402, conductor 19, conductor 102, contact and armature 6 of relay 101, conductor 104, inner right contact and armature of relay 2T to ground. It is to be noted that battery feed relay 701 is energized in series with any of the translator register relays which is energized. I

The energizing circults. for relays 6H, 8E, and 703 are believed to be obvious and need not be traced in detail. It shouldbe noted that the contacts appearing in the lower right-hand corner of Fig. 1 are controlled by relays 101 and 105 of Fig. 2.

As soon as the record'is registered 1n the translator, a circuit is completed from grounded battery, Winding of translator control relay 1001 (Fig. 10), conductor 1002, conductor 704, left front contact and armature of relay 701 to ground.

Relay 1001 is a multi-contact relay and controls a row of contacts shownin Figs. 10 and 11, to connect 22 pairs of test relays to 22 test conductors extending to translator relays. These test relays determine the par ticular letters to be printed.

In printing the word THE no translation is required, since the letters to be printed correspond to the keys depressed.

The energization of relay 1001 causes the energization of all the test relay pairs, with the exception of the pairs 1013, 1014, 1024, 1025, 1031 and 1032.

The circuit for relays 1003 and 1004 (corresponding to the letter S) may be traced from grounded battery, winding of relay 1003, conductor 1005, winding of relay 1004, conductor 1006, back contact and armature 1 of relay 1007, front contact and armature 1 of 3 1001, onductor 1008, conductor 704,

conductor 403, armature 2 and back contact of unoperated relay 15 to ground. .Relays 1003 and 1004, upon energization, lock in a circuit through the left armature and front contact of relay 1003, conductors 1009, 1010, 705 and 801, back contact and armature 3 of relay 802, conductors 803 and 706, right armature and back contact of relay 707 to ground.

Other test relays 1021, 1044, 1022,1035, 1023, 1034, 1030', 1037, 1033, 1038, 1042, 1039, 1043, 1040, 1036,1041, 1101, 1115, 1102, 1116, 1103, 1117, 1104., 1118, 1105, 1119, 110e, 1112, 1107, 1120, 1103, 1113, 1109, 1121, 1110 and 1122 are energized and locked in circuits similar to those Just traced for relays 1003 and 1004.

It is obvious that with the translator relays 2T, 6H and 8E energized, the corresponding pairs of test relays 1013, 1014, 1024, 1025, 1031 and 1032 cannot be energized.

To allow time for the test relays to operate and lock, the relay 1007 is made slow to operate. The circuit for relay 1007 may be traced from grounded battery, Winding of relay v1007, left armature and front contact of re ay 1001', conductor 1002, conductor 704, left front contact and armature of relay 701 to ground.

When relay 1007 operates, it places ground potential on the printing lead 1020, thus operating the magnet which controls the typing of the letter T, in a circuit from ground, armature 4 and contact of relay 1007, conductor 1020, right armature and front contact of relay 1004, conductor 1012, right armature and back contact of relay 1013, armature 3 and back contact of relay 1014, conductor 1015, armature 2 and front contact of relay 1007, armature 2 and front contact of relay 1001, conductor 1016, conductor 707, conductor 404, armature 6 and front contact of relay 2T conductor 405, armature 10 and back contact of relay 4P, conductor 406, armature 7 and back contact of relay 3K, conductor 407, conductor 501, conductor 804, armature 4 and back contact of relay 805 to the conductor designated T, which extends through the winding of the typewriter magnet controlling the letter T to grounded battery.

Only one of the key-operating magnets has been shown in Fig. 8, and that one is designated 806 and controls the typing of the letter I. It is to be noted that each of the key-operating magnets controls an armature and contact like the one shown on the drawing for magnet 806. It should be further noted that these armatures and cont-acts are all connected in multiple, so that whenever a key-operating magnet is energized, a circuit is completed across the conductors shown as terminating in the armature and contact of magnet 806. The multiple connection is indicated on the drawings.
